The valve stem is made of high-performance stainless steel material with good corrosion resistance. The sealing materials are fluororubber (FPM) and carbonized PTFE+C, which have the characteristics of high strength, high temperature and high pressure resistance, and corrosion resistance. The valve body material uses high-strength carbon steel that is the same as the pipeline, which will not cause uneven stress, nor will it deform due to earthquakes or vehicles passing through the ground. The pipeline is resistant to aging, and other connection methods such as flanges can be selected according to customer needs;

The sphere is made of high-performance stainless steel, and the entire processing process is tracked and detected by advanced computer detectors, so the machining accuracy of the sphere is very high, making the operation easy and without any adverse interference;

; The valve stem adopts explosion-proof design and is used;       The entire assembly process of the valve is completed at a constant temperature, ensuring product quality; Compared with products of the same specifications in the same industry, the valve body design, small appearance, and beautiful appearance; Under the condition of ensuring normal operation and use of the valve, the service life can reach more than 20 years.
